       2. The stick according to claim 1 wherein said cue tip is connected to said central body (1) by means of a coupling having a screw comprising two threaded portions (8) and (8') opposite one to the other, said threaded portions being separated by two planar portions (9) and (9') opposite one to the other, whereby the rear end of said cue tip (2) is blocked against the central body (1) when rotated about a quarter of a revolution. 
     
     
       3. The stick according to claim 1 wherein said hand grip (4) has a forward end and a rear end and is disassemblable in the rear end thereof, has an internally threaded opening (22) and is provided with a knurled disc (18), said disc having two threaded pins (20) and (21), said threaded pin (20) engaging with the internally threaded opening (22), and a plurality of weights (23) which are fixed to said threaded pin (21) whereby the weight of the stick may be varied depending upon the requirements of the player. 
     
     
       4. The stick according to claim 1 wherein said central body (1) has a cylindrical cavity (29), and a nut (27) which is inserted within said cylindrical cavity, said cue tip (2 has a threaded stem (26) emerging therefrom, a sleeve made of expandable rubber (25) mounted on said threaded stem (26) said stem engaging said nut (27), whereby said central body (1) is connected to said cue tip (2), and whereby said sleeve (25) expands in the interior of said cavity (29) so that the connection between said central body (1) and said cue tip (2) is firm. 
     
     
       5. The stick according to claim 4 wherein the head (3) of said cue tip is provided with a stem (30), said stem being partially threaded, said stem engaging a nut (31), said nut being located within a cylindrical cavity (32) formed in the forward end of said cue tip, a sleeve (33) made of rubber is interposed between said cue tip and said head, said sleeve expanding when said stem (30) is screwed on said nut, whereby the forward end of said cue tip is blocked, and said head (3) is replaceable with a new head according to the requirements of the game. 
     
     
       6. The stick according to claim 1 wherein said central body (1) has a trunco-conical surface (34) at the rear end thereof, said hand grip has a forward portion, said forward portion of said hand grip (4) engaging with the trunco-conical portion of said central body when the stick is assembled.
